I seriously doubt your B12 is the culprit. However if the shots were in cyano form ...and you cannot convert it... it would not be working in the cells at all. But it would be in the blood.

The test to see if you are utilizing your B12 is the MMA blood test.
If the MMA comes back low, that means you are using the B12 normally. It is less expensive than DNA testing for the genetic polymorphism. The range for B12 still goes down to 200, and that is out of date. The new low is now 400 and hence 800 is not high at all.

B6 however, does not need to be given in high doses. High doses of vitamins over time can create a "dependency" situation, where the enzymes change and "need" high doses.
Discontinuing can create therefore deficiency symptoms. This was first discovered with Vit C...massive doses discontinued after a time, created a scurvy reaction, when they were not
deficient.

This is the skinny on B6 toxicity...

It started with the PMS old treatments of 500mg or more a day of B6. That is when most of the few accounts were discovered.
Quote:
High intakes of vitamin B6 from food sources have not been reported to cause adverse effects [1]. However, chronic administration of 1–6 g oral pyridoxine per day for 12–40 months can cause severe and progressive sensory neuropathy characterized by ataxia (loss of control of bodily movements) [7,29-32]. Symptom severity appears to be dose dependent, and the symptoms usually stop if the patient discontinues the pyridoxine supplements as soon as the neurologic symptoms appear. Other effects of excessive vitamin B6 intakes include painful, disfiguring dermatological lesions; photosensitivity; and gastrointestinal symptoms, such as nausea and heartburn [1,2,29].
The blood ranges of vitamins really are not that accurate. Your B12 is not alarming IMO at all. The ranges were done many years ago, on people at random. It is important however to make sure you are utilizing B12 properly...because if not...you could be deficient when using cyano type and still testing high.
